Copper Nickel is highly resistant to corrosion in seawater because its electrode potential is adjusted to be neutral with regard to seawater. Because of this, it is used for piping, heat exchangers and condensers in seawater systems, as well as marine hardware.

Copper Nickel C706 is also known as Copper Nickel 90/10 because it is made up of 10% nickel or as ASTM B466 and ASME SB466. C706 is known for its moderate strength, weldability, and formability. The inclusion of controlled quantities of iron and manganese also give the 90/10 alloy an extraordinary resistance to general corrosion and stress cracking, as well as to erosion and impingement due to turbulent water containing air bubbles and silt flowing at high velocities.
Due to the specific properties of nickel and copper alloys, they are applied in a variety of Navy, Commercial Marine, and Offshore industrial applications.
Copper-nickel UNS C70600 has a copper content of not less than 88.6%.
Tabulated below are the mechanical properties of UNS C70600 tubes as a function of heat treatment.
